UNITED STATES PATENT OEED HIRAM L. GRISELL, OF PENNVILLE, INDIANA, ASSIGNOR TO HIMSELF AND LEVIS GRISELL.

IMPROVEM ENT IN SCALE-BEAMS.

Specification forming part of Letters Patent No. 207,735, (lated Sptembel 3, 1373; RDPICIIOH flied Millcll 25, 1878.

To all whom it may concern:

Be it known that I, HTRAM L. GRI'SELL, of Pennville, in the county of J ay and State of Indiana, have invented certain new and useful Improvements in Scale-Beams; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My present invention is intended as an improvement upon Let-ters Patent- No. 178,629, granted to me June 13, 187 6; and the nature of my invention consists in a revolving cylinder provided with calculating-tables on its surface, and mounted in arms that may be attached to the scale-beam of any scale, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure l is a side view, and Fig. 2 an cnd view, of my invention.

A represents the scale-beam of any ordinary beam-scale. At or near each end of this beam is, by means of a set-screw, a, secured an arm, B, the outer end of which has a suitable perforation to receive the pivot d of an elongated cylinder, D. This cylinder is thus pivoted and rotates in the arms B B. The scale thus becomes a double-beam scale, and the cylinder may be arranged in han gers under the beam as well as in the arms on one side.

The cylinder D is, on its surface, provided with calculating-tables, substantially the same asin my former patent above referred to, or any other calculating-tables may be applied to or afxed thereon.

C is a movable ring placed around the c vlinder, as shown, to balance the beam. This cylinder may be attached to either an equalbalanced or a beamed scale. Any side ofthe cylinder can be brought into view by revolv ing the same in its bearings.

Persons using scales can procure the latest improvement in a calculating-beam Without purchasinga new scale.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improvement on Letters Patent No. 17 8,629, dated June 13, 1876, the rotating cylinder D, provided with calculating-tables on its surface, and hung by pivots d d in arms B B, which are detachably secured to an ordinary scale-beam, A, by means of set-screws c a, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

H. L. GRISELL.
